nasa mars evolution
Bookmarked 638 weeks ago billions of years ago when the red planet was young it appears to have had a thick atmosphere that was warm enough to support oceans of liquid water - a critical ingredient for life the animation shows how the surface of mars might have appeared during this ancient clement period beginning with a flyover of a martian lake the artist039s concept is based on evidence that mars was once very different rapidly moving clouds suggest the passage of time and the shift from a warm and wet to a cold and dry climate is shown as the animation progresses the lakes dry up while the atmosphere gradually transitions from earthlike blue skies to the dusty pink and tan hues seen on mars today his video is public domain and can be downloaded at: http:svsgsfcnasagovgoto20201like our videos subscribe to nasa039s goddard shorts hd podcast:http:svsgsfcnasagovvisitunesf0004_indexhtmlor find nasa goddard space flight center on facebook:http:wwwfacebookcomnasagsfcor find us on twitter:http:twittercomnasagoddard |

super-earths: new planets found
Bookmarked 658 weeks ago astronomers working at the european southern observatory eso in chile have discovered seven planets orbiting the star gliese 667ctwo exoplanets have been discovered in the star039s habitable zone which has just the right range of distance where liquid water can exist on a planet039s surfacea super-earth is an extrasolar planet with a mass higher than earth039s but substantially below the mass of the solar system039s smaller gas giants uranus and neptune which are both more or less 15 earth massesthe term super-earth refers only to the mass of the planet and does not imply anything about the surface conditions or habitabilityastronomers at the european southern observatory in chile found out that 40 per cent of red dwarves are orbited by super-earths red dwarfs are by far the most common type of star in the milky way galaxy so there might be tens of billions of such planets in our galaxy alone |

titan039s chemical cocktail
Bookmarked 641 weeks ago dive into titan039s thick atmosphere and find out what a strange place it is adapted from nasa039s scientific visualization studio with its clouds rain cycle and giant lakes saturn039s large moon titan is a surprisingly earthlike place but unlike on earth titan039s surface is far too cold for liquid water - instead titan039s clouds rain and lakes consist of liquid hydrocarbons like methane and ethane which exist as gases here on earth when these hydrocarbons evaporate and encounter ultraviolet radiation in titan039s upper atmosphere some of the molecules are broken apart and reassembled into longer hydrocarbons like ethylene and propanenasa039s voyager 1 spacecraft first revealed the presence of several species of atmospheric hydrocarbons when it flew by titan in 1980 but one molecule was curiously missing - propylene the main ingredient in plastic number 5 now thanks to nasa039s cassini spacecraft scientists have detected propylene on titan for the first time solving a long-standing mystery about the solar system039s most earthlike moon |

nasa mars atmosphere loss: neutral processes
Bookmarked 639 weeks ago when you take a look at mars you probably wouldn039t think that it looks like a nice place to live it039s dry it039s dusty and there039s practically no atmosphere but some scientists think that mars may have once looked like a much nicer place to live with a thicker atmosphere cloudy skies and possibly even liquid water flowing over the surface so how did mars transform from a warm wet world to a cold barren desert nasa039s maven spacecraft will give us a clearer idea of how mars lost its atmosphere and thus its water and scientists think that several processes have had an impactscientists think that the collision of neutral hydrogen molecules may have helped to drive the martian atmosphere into space over billions of yearsthis video is public domain and can be downloaded at: http:svsgsfcnasagovgoto11037 like our videos subscribe to nasa039s goddard shorts hd podcast:http:svsgsfcnasagovvisitunesf0004_indexhtmlor find nasa goddard space flight center on facebook:http:wwwfacebookcomnasagsfcor find us on twitter:http:twittercomnasagoddard |

robonaut supports telemedicine advances
Bookmarked 629 weeks ago nasa is always investigating new uses for one of the world039s most advanced humanoid robots robonaut 2 r2 working with dr zsolt garami from houston methodist research institute r2 was put through the paces to prove its use as a device enabling telemedicine or the use of electronic communications to conduct medical procedures after some quick training an r2 teleoperator was able to guide the robot and perform an ultrasound scan on a medical mannequin humans at the controls are able to perform the task correctly and efficiently by using r2039s dexterity to apply the appropriate level of force and can track their progress using r2039s vision system the teleoperated r2 also experimented using a syringe as part of a procedure further demonstrating the robot039s capabilities for telemedicine this demonstration of robotic capabilities could one day result in the ability for physicians to conduct complex medical procedures on humans in remote locations whether on the earth039s surface or even in low earth orbit |

sentinel-1 quick steps to launch
Bookmarked 609 weeks ago this time-lapse video shows sentinel-1a being prepared for launch and its final lift off on 3 april 2014 from europe039s spaceport in french guiana it features a deployment test of the satellite039s 12-m long radar and shows the satellite being hoisted onto the soyuz rocket039s fregat upper stage followed by encapsulation within the fairing this 039upper composite039 is then transferred to the launch pad where it joins the rest of the soyuz and then is launched into orbit around earththis first sentinel satellite carries an advanced radar to scan earth039s surface in all weather conditions and regardless of whether it is day or night now in orbit it will be used to care for many aspects of our environment from detecting and tracking oil spills and mapping sea ice to monitoring movement in land surfaces and mapping changes in the way land is used credit: esa--s corvaja m pedoussaut 2014 |
